I agree 100% with mojo (1)
However, IMHO, the criminal justice system is too slow,
too expensive, too bureaucratic, etc to deal with these felonies
in a socially effective way, i.e. to protect society, punish
lawbreakers & dissuade others from breaking the law.

In my experience, thugs like some of these union goons,
with possibly the support of 99+% of the rest of the union
‘members’, only respond to one thing that both stops
their ‘criminal assaults & batteries’ & makes sure that
they never ‘threaten’ another peaceful citizen again!
What you have to say afterwards is,”Officer, we were only
defending ourselves after they attacked us”.
